i am working on an application where we need to scan QR codes for iPhone.
I am using zxing API for it. App is working great with iOS 6.0.1 but it's not working right with the latest release of iOS 6.0.2.
I am sending the scanned QR code to the server which gives me this response.
For example, if the QR code is 00012123456789000134,
iOS 6.0.1 version is giving me 00012123456789000134 as result but iOS 6.0.2 gives the result as 2100012123456789000134\u001D0111223344556677.
I don't know what is the problem. Is it due to the fixes in iOS 6.0.2 ????
Please help me out.
Thanx in advance.
Have you tried to scan with ZXing's own scan app from the app store, you need to check that out first to make sure that the problem is not the SDK nor the QR Code you are scanning.
If it is related to your code, review how you the result string is handled and moved to the output. it can be any of a few things, Zombies, incompatible types and moving between them, but mostly logic error. If you can post your codes, a lot more people will probably be able to help you. Also always the thing that ultimately helps is a lot of printfs.

Try to download this API from this link: https://github.com/Lascorbe/LASharekit
Its working fine for me. Merge this into your App.
I downloaded the latest version of VMPinterest framework (they have released a new version) and it does works perfectly with iPad (i have tested for ipad mini).
I would recommend VMPinterest framework. as unlike others it doesnt take you to web page but it directly get you post the image remotely.
They have also released a demo app using this framework - is live on appstore..
App link https://itunes.apple.com/us/app/vmpinterest/id607998053?ls=1&mt=8
So the framework is appstore approved.
Its compatible with iOS 4.3 and above and runs on iPod touch/iPhone/iPhone5/iPad/iPad mini

Is there any other methods to stop ARC in IOS 5?
How to overcome this?
Any one plz provide me the link for downloading the Facebook API for IOS 5...
If you use official SDK, you should compile it as a static library, not with your code, and then link your app with that library. You could see how it is done in SDK examples, and also here is some information about building process. Hope it will help.
Here is the link with working Source Code:

Can I really do that with the phone? Perhaps I would have to call any of the native API's, but I am not really sure whether and what is possible. I am pretty sure that the camera is accessible, so at the worst case I could send the picture to the server, decode the QR code on the server, and get the results on the phone, right ?
There's a QR code reading class here: http://www.libspark.org/wiki/QRCodeReader/en and some instructions on how to use it: http://blog.jactionscripters.com/2009/05/23/introduction-of-qr-code-reader-library/
While I've never done it, iOS does support the camera as far as I know so it should work just fine. The code is pretty similar to using a webcam.
And here's a library which claims to be improved: http://www.kasperkamperman.com/blog/flash-qrcode-reader-as3/
If you are working on a iOS (iPhone or iPad) project, i recommend you qr-zbar-ane native extension. You can find download links and sample code at : http://www.nativext.com/ane-by-os/ios/qr-reader-native-extension/
We're creating an iOS app that basically scans badges at events and collects contact info. We're looking for an iOS library that can read not only the number of the barcode, but also any additional information that's included (contact info). Does anyone have any library suggestions or will this have to be a custom library? Thanks in advance!
Updated:
Use AVCaptureMetaDataOutput in AVFoundation which works with minimum deployment target iOS 7.
Previous Answer:
Have been using ZBar SDK in most of our projects. Picks up barcode and scans very fast, easy to customize focus area from SDK. Tested on iPhone 3GS, iPhone4/4S, iPhone 5 and iPad
https://codeload.github.com/cgreening/BarCodeExample/zip/master
iOS7 has built in functionality scanning BarCodes not sepearate sdk is required; if your deployment target is iOS7
Is your barcode format up to you, or do you have a predetermined symbology you have to work with?
There is this: http://shopsavvy.mobi/sdk/. Don't know why that wouldn't work for you, unless you object to the licensing terms.
Checkout ZXing ("Zebra Crossing") at http://code.google.com/p/zxing/
Reads almost every kind of barcodes and we used it with great success previously.
Use ZBAR its the best, we used it in our app www.infomq.com and its is really stable and scans reliably.
Basically you want to use PDF417 which is a stacked linear barcode symbol. Check out the pdf417 decode on Sourceforge.
I am newbie to iPhone application. But recently I saw a post asking for Barcode Reader for 3G iPhones. And people(including me) have referred to zxing which works on 3GS or later and if you want to make an appication for 3G then better you buy it from QuickMark or RedLaser to get 3g scanning.
So I planned something and need several information from you all
There are lots available on appStore. One of them is pic2shop(Which is a free application).
But what I want to know is:
What exactly is it done to recognize the barcode and generate code?
Is there any website or link to which when image of barcode is send will respond with the code generated or any API which does the same i.e. Taking picture and generating code.
And Secondly From Where does we get the information about the produce related to that barcode code.
Hi we recently had a product which required bar code scanning functionality, in the end after evaluating a lot options we went with zBar but it does not work on iPhone 3G it requires 3GS or above.
zBar is an open source SDK you can download it from sourceforge.
What we're doing right now is scanning bar codes using the zbar SDK & then calling upcdatabase.com API through xml-rpc to get the information about the product back.
And its working pretty well.
If you do not want to pay redlaser or others for SDK I would recommend using this approach. But of-course the downside is iphone 3G is not supported which I think does not represent many devices & also recently Apple has also dropped its support for its upgrades as iPhone 3G users will not be able to upgrade to iOS 4.3.
I actually own a 3G iphone & its very slow on iOS version 4.0 .
